Built a PC 3-4+ years ago (i9-9900k) on a Z390 Gigabyte Designare motherboard, 64GB memory, 2TB NVME SSD, Seasonic Prime 1000 Titanium SSR-1000TR PSU.
Specs:
Gigabyte Z390 DESIGNARE
Memory: 64GB
Disk: Samsung NVME 990 PRO 2TB
Graphics: NVIDIA GeForce GTX 1660 (not using the machine for gaming)
BluRay: PIONEER BD-RW BDR-209M (2)
Network: Intel X550-T2 (10GbE)
Other I/O cards: I used to have a StarTech USB-C 3.1 or 3.2 PCI-e card in the machine but I have since removed for troubleshooting as I was not using that often.
I started out with Windows 10 Pro during the initial install, I have re-installed Windows 10 Pro, eventually moved to Windows 11 Pro (upgrade) and later reinstalled fresh.
I have swapped the SSD from a Samsung 2TB EVO to a Samsung 2TB PRO, yet I continue to experience semi-frequent crashes.
I have run memtest86 and memtest86+ the memory checks out good, I have always run the latest BIOS (F10) as of this posting. I am not overclocking, mostly using BIOS defaults for everything except the boot order.
Over the past few months, I have had 5 crashes so far. I am somewhat familiar with troubleshooting when on Linux (except for the [14900k issue](Debian Linux Stable on Pro WS W680-ACE IPMI (application segfaults, kernel panic) - #10 by jpiszcz which @wendell and team helped with) I recently ran into); however, on Windows, given that this issue occurs on Windows 10, a fresh Windows 10 install and Windows 11 upgrade and a fresh Windows 11 install, I am not sure what else I can do or check?
Symptoms:
The crashes almost ALWAYS happen when the machine is idle. Only one or two times in the past few years I have caught the BSOD when it happens live.
Attached are two screenshots of the last 5 bluescreens and the filenames associated with the crashes. Microsoft recommended I update the Intel ME Firmware, which I did and I though that had fixed it but the BSODs continued to occur.
Does anyone have any potential thoughts or ideas what else this issue could be or has anyone else run into something like this before? I presume the i9-9900k CPUs were OK(?) and did not have any issues?
